6.2.1 System log
The Daniel 3410 Series Gas Ultrasonic Flow Meter meter logs all system messages in the system
log. The meter can store up to 3000 system records. The user can select whether old, unread
records can be overwritten by new records when the log becomes full via the data point
DoOverwriteUnreadSystemLog. This point can be modified using the Daniel MeterLink
Tools|Edit/Compare Configuration screen. The default is to overwrite old, unread records. Refer
to “Options for reading audit, alarm, and/or system log records” for information on reading
records and marking records as read. The data point
IsSystemLogFull indicates whether or not
the system log is full and cannot overwrite old, unread records.
Repetitive system messages are prevented from filling up the system log. When a particular
system message occurs 3 times within 60 seconds, that system message is suppressed until that
message’s frequency drops below the 3 times-per-60 sec rate.
The system log records indicate
when a system message suppression is started and ended.
6.2.2 Reading log records
Daniel 3410 Series Ultrasonic Flow Meter log records are read using the Daniel MeterLink

• daily
• hourly

Select the desired log group(s) via the
